corporation of Michigan Application September 23, 1938, Serial Ito. 231,284 1 Claim. (CL 20-69) 1y comprises a strip of rubber that is applied around the edge portion of the door-and usually consists of a continuous strip in orderithat there will be only one joint. Obviously such strips must be bent'a't, relatively sharp angles in order to followthe contour of the door. When the strips are formed of molded rubber they become desealed spaces therefore result. Sponge rubber strips have'been-more generally used because they provide a seal even though they are somewhat deformed whenbent around the door.

. However, the sponge rubber strips while providv ing a satisfactory seal 3 have the disadvantage that they are porousand retain moisture which causes rusting of the adjacent metal surfaces.

An object of this invention is'to provide -a hollow, door sealing strip that can be bent for assembly without deformationthat will cause leaks.

and which at the same time has a contact portion that is sufliciently flexible to be readily deformed by the door when in closed position.

. Another object of the invention is to provide a rubber sealing strip for doors that is'impervi'o'us to moisture and can be applied to follow the door contour without distortion such that the sealing efllciency will be impaired.

Another object of the invention is to'- provide a hollow moldedrubber sealing strip with interior reinforcements that will resist collapsing when the strip is bent to assembled form.-

Another object of the invention is to provide o a tubular interiorly-reinforced rubber sealin strip having a contact sector that is more readily collapsible than the remaining portion. 7

A further object of the invention is to pro-- vide a moldedrubber sealing strip having three 45 sectors, one of which is more readily deformable than the other two.

Other objectsot the invention'will appear from the following description taken in connection with the drawing, which forms apart of this 50;

specification, and in which: Fig. 1 is a fragmentary side elevational view of a rear portion of a motor vehicle showing the invention associated with a rear door; 55 v I g Fig. 2 is a fragmentary vertical sectional viewinserted into the openings in the lamb rail and edge of the base for the purpose of covering showing the door with which the invention is associated about to contact 'the door jamb;

Fig. 3 is a view similar to Fig. 2 showing the door in closed position;

Fig. 4 is a-sectional and perspective view of the sealing strip of the invention;

Fig. 5 is a perspective and sectional view of the modified form of sealing strip.

The invention is shown applied to a rear door ID of a conventional form of motor,vehicle H.

The door is comp6sedof an outer panel I! and an innervpanel l3 having its outer portion bent outwardlyand then vertically to form. a jarnb rail l4 and a vertical edge ii that the edge portion I6 of the outer panel is crimped over.

The door fits into an opening in the body -.structure that is formed by-a wall formation as best shown in Figs. 2 and 3/ This wall formation includes an outer panel II that is bent inwardly forming a transverse surface l8, then upwardly forming a vertical surface l9 and then transversely form'inga surface 20. thesurfaces l8, l9 and 20 forming the door jamb.

Sealing means for the space between the door and door jamb, forming the subject of this invention, comprises a strip indicated generally at 2| and securing clips 22. The strip is preferably formed as a unitary rubber structure that is impervious to moisture and comprises a flat base 23, a'tubular section 24 and-a neck 25 joining the tubular portion with the base. Projecting from the tubular section adjacent one side of the neck is acurved flexible flange 26 that is coextensive with and arranged to overlie one the fastening clips that would otherwise be exposed to view. Another flexible flange 21 forms a part of the strip and is coextensive with and projects from the tubular section; substantially diametric to flange 26. This flange 2,1 is of angular cross-section and is located and arranged to lie against the edge portion of the door in sealing relation therewith when the, strip is .ap- I plied to the jamb rail.. v

The transverse jamb. rail ll of the door is formed with a plurality of openings 28 through which the head of the spring steelclips 22 can bev inserted when contracted. The spring clips are preferably formed of a single piece of wire 29 extend, the arms being curved to embrace theedges of the base portion, ofthe strip. After the clips are snapped onto the base portion of the strip the heads thereof are contracted and that is bent to form the head from which arms of the tubular structure so that it can be bent around the door without collapsing sufiiciently to cause spaces through which air can leak when the door is closed. In the preferred form of the invention shown in Figs. 2, 3 and 4, such reinforcing webs are generally in the form of a Y and they reinforce the tubular section of the strip in a plurality of directions. The webs are arranged to resist deformation of the tubular section of the strip when bent around the'edge of the door so that collapsing of such section at the bent portions is prevented. The sector 33 of the tubular section of the strip forms the contact surface for engaging the door Jamb when the door is closed and it will be noted that this sector is larger and thus more readily deformed than the other sectors. will fiex readily when engaging the door, Jamb to provide the desirable leak-proof seal upon the application of the usual force used in closing the door. The interior webs stiffen the tubular section of the sealing strip where required to maintain a desired cross sectional form at the bends when applied to a door and leave a sealing contact sector surface that can be more readily deformed than-the other sector surfaces.

Thus the contact sector In the modified form of strip shown in P18. 5, the structure is substantially the same except that the flange I8 terminates in an angular edge 43 instead of in a blunt edge as shown in the preferred form of the invention, and the web structure within the generally tubular section of the strip instead of being in general Y form consists of a straight web 4i extending centrally through the interior and a straight web 42 joining one side of the web I with the interior surface of the tubular section and extending normal to the web ll. the flange 28 projects is of larger area and thus more flexible in the modified form of the invention than the corresponding sector in the preferred form of the invention. For some uses this modified construction is desirable.

Although the invention has been described in connection with a specific embodiment, the principles involved are susceptible of numerous other applications which will readily occur to persons skilled in the art. The invention is therefore to be limited only as indicated by the scope of the appended claim,

What is claimed is: A rubber weather strip comprising a relatively fiat solid anchor portion, a tubular portion joined to one face of the anchor portion, a reinforcing allel with the anchor portion Joined to the dia- The contact sector from which
